本文主要是介绍Influxdb系列（二）influx Cli工具操作influxdb，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、安装并使用 influx CLI
客户端下载地址：https://docs.influxdata.com/influxdb/v2/tools/influx-cli/
[root@192 bin]# tar -xvzf influxdb2-client-2.7.3-linux-amd64.tar.gz
[root@192 bin]# cp influx /usr/local/bin/
二、客户端方式创建用户
相关的官网地址可直接查看如下地址：
https://docs.influxdata.com/influxdb/v2/install/?t=Set+up+with+the+CLI
https://docs.influxdata.com/influxdb/v2/admin/tokens/create-token/#create-a-token-using-the-influx-cli
[root@localhost influxdb2-2.7.3]# ./influx setup \--username dameng \--password dameng123. \--token dameng123 \--org dameng \--bucket sqllog \--retention 3d \--force
User Organization Bucket
dameng dameng sqllog## 创建token
[root@localhost influxdb2-2.7.3]# ./influx auth create -o dameng --all-access
ID Description Token User Name User ID Permissions

https://docs.influxdata.com/influxdb/v2/admin/buckets/create-bucket/?t=influx+CLIinflux bucket create \--name my-bucket \--org my-org \--retention 72h三、创建配置文件_token认证
https://docs.influxdata.com/influxdb/v2/tools/influx-cli/
[root@192 bin]# ./influx config create --config-name influx.conf --host-url http://localhost:8086 --org dameng --token PMDQZts55MPX8LVnM7tr9dbA3_3_qwdyWnM0dBiLHzmNyjWOi1hIFJQFXFbssvUc2yJ8fpdQhDut4FUBzvN3qg== --active
Active Name URL Org
* influx.conf http://localhost:8086 dameng## 配置文件
[root@192 bin]# ll /root/.influxdbv2/configs
-rw-------. 1 root root 505 11月 4 20:33 /root/.influxdbv2/configs
四、InfluxQL语法
（一）DBRP映射
https://docs.influxdata.com/influxdb/v2/query-data/influxql/dbrp/
查询实体与DB的映射
- InfluxQL 需要数据库和保留策略 (DBRP) 组合才能查询数据。在 InfluxDB 2.7中，数据库和保留策略已合并并被 InfluxDB存储桶取代。要使用 InfluxQL 查询 InfluxDB 2.7，指定的 DBRP 组合必须映射到存储桶。
- InfluxDB 2.7将在以下操作过程中自动创建 DBRP 映射
[root@192 bin]# influx v1 dbrp list
ID Database Bucket ID Retention Policy Default Organization IDVIRTUAL DBRP MAPPINGS (READ-ONLY)
----------------------------------
ID Database Bucket ID Retention Policy Default Organization ID

https://docs.influxdata.com/influxdb/v2/query-data/influxql/explore-data/
# 进入数据库
[root@192 bin]# influx v1 shell
# 使用数据库
> use "sqllog"
select execSqlStr from SqlEntity LIMIT 1;select execSqlStr from SqlEntity where entityType =3 LIMIT 5;## 计算条数五、其他的命令
https://docs.influxdata.com/influxdb/v2/reference/cli/influx/auth/list/
influx auth list
